# lame quickie script to snarf a core of a hung asterisk process.

# we have found that gcore doesn't yield as useful a core file
|
|
|
|
|
# as that yielded by a signal-caused core dump. So we are going to change
|
|
|
|
|
# the strategy to sending a SEGV signal to the asterisk process,
|
|
|
|
|
# and have it 'burn to the ground', leaving behind a core file.
|
|
|
|
|
# the main difference is that you cannot control where the
|
|
|
|
|
# core file will end up. We will assume that safe_asterisk was
|
|
|
|
|
# used to start asterisk, and the core file should therefore end
|
|
|
|
|
# up in /tmp (because safe_asterisk cd's there before starting asterisk).
|
|
|
|
|
# if this is not the case, set DUMPDIR to the place where the core
|
|
|
|
|
# file can be found.
